菜鸟刚开始学习使用icc，尝试着跟着student user guide做每一步任务，在使用icc过程中create_mw_lib后遇见了许多自己无法解决的问题，发帖在此求助，希望各位高手能够指点我一下，不甚感激！
1.我所书写的tcl命令如下
set MW_lib {/home/wtt/test/CIC/pt/lib/smic18}
set search_path {search_path + /EDATools/SMIC/SMIC_018um_HOME/aci/sc-m/synopsys + /EDATools/SMIC/SMIC_018um_HOME/aci/sc-m/map + /EDAVendor/Synopsys/DC-2010.03-SP1/libraries/syn + /EDATools/SMIC/SMIC_018um_HOME/aci/sc-x/tlf + ../in + ../io + ./script + ../lib + $MW_lib}
set link_library [list ff_1v98_0c.db ff_1v98_m40c.db ss_1v62_125c.db tt_1v8_25c.db]
set target_library [list tt_1v8_25c.db ss_1v62_125c.db ff_1v98_0c.db ff_1v98_m40c.db]
set symbol_library [list smic18m.sdb]
create_mw_lib design_cic -open \
-technology {../lib/smic18_6lm.tf} \
-mw_reference_library {/home/wtt/test/CIC/pt/lib/smic18}
set_check_library_options -all
check_library
set_tlu_plus_files \
-max_tluplus fast.tlf \
-min_tluplus slow.tlf \
-tech2itf_map streamOut.map
check_tlu_plus_files
read_verilog -dirty_netlist ../in/cic_top.v
current_design CIC_TOP
check_design
uniquify
link
save_mw_cel -as CIC_TOP
list_libs
exit
2.在load tf文件时候出现了如下的warning,请问这是否需要引起重视呢？
Start to load technology file ../lib/smic18_6lm.tf.
Warning: ContactCode 'CONT1' is missing the attribute 'unitMinResistance'. (line 480) (TFCHK-014)

Technology file ../lib/smic18_6lm.tf has been loaded successfully.
3. 在开始check library 后出现这样的一句话，是否是我设置mw没有成功呢？
#BEGIN_XCHECK_LOGICCELLS
All 478 physical cells in design_cic are missing in logic library.
/home/wtt/test/CIC/pt/lib/smic18 are missing in logic library.
#END_XCHECK_LOGICCELLS
#BEGIN_XCHECK_PHYSICALCELLS
All 2472 logic cells in ff_1v98_0c
ff_1v98_m40c
ss_1v62_125c
tt_1v8_25c
are missing in physical library.
#END_XCHECK_PHYSICALCELLS
4. check library时候的一个error, 我没有看明白是什么意思，请大家指导，谢谢！

5. check library中的 check tech项遇见很多warning, 也不明白是什么意思，同求指导

6. 在导入verilog 设计后出现许多undefined module，麻烦大神们给我解释解释吧！
Compiling source file /home/wtt/test/CIC/pt/in/cic_top.v
Warning: Cell 'ADDHX1M.CEL' is created for undefined module 'ADDHX1M'. (MWNL-294)
Warning: Cell 'XOR2X1M.CEL' is created for undefined module 'XOR2X1M'. (MWNL-294)
Warning: Cell 'CLKINVX1M.CEL' is created for undefined module 'CLKINVX1M'. (MWNL-294)
Warning: Cell 'NOR2X1M.CEL' is created for undefined module 'NOR2X1M'. (MWNL-294)
7.导入design后，命令check design,uniquify 出现logic cell在physical library 里面不匹配的warning, 然后出现error
Information: linking reference library : /home/wtt/test/CIC/pt/lib/smic18. (PSYN-878)
Warning: The 'XOR2XL' cell in the '/home/wtt/test/CIC/pt/lib/smic18' physical library does not
